RE: MSP430FR59941: unable to write to ADC12CTL0
>while (!(Stat & BIT0)) //always BIT0 >Stat=ADC12IFGR0;; How (and where) is Stat declared? Just from this fragment, it looks as though you may be checking stale status. The reason it may be interesting is ADC42 [Ref Errata sheet (SLAZ681M...

MSP430FR59941: Internal temp sensing accuracy?
TI Thinks Resolved
Part Number:
MSP430FR59941
Hi MSP430 team, I currently have a customer that is wondering what the accuracy of the internal temp sensor for the
MSP430FR59941
is. Please see the question below. I did a quick look in the datasheet and their is an offset...

RE: MSP430FR59941: configure LFXO
Thanks, Bruce: Believe it is working. You won't believe what I was doing. I was using another timer (also driven from ACLK). The other timer was timing out every .01 sec. So naturally no matter what the (common) clock source was, the time difference...

RE: CCS/MSP430FR59941: Enabling of the SYSNMI interrupt
Hi Connor, I don't think the code examples include this because the NMI source is internal, not external. Your customer's code looks right after reviewing the user's guide. My only comment would be to ensure SYSNMI is 0 in the SFRRPCR register...

RE: CCS/MSP430FR59941: Compiler option to use 32-bit variables
It turns out that the issue was related to how the variable was being displayed with printf. With previous GNU tools on linux system a %u or %d did not require a %lu or %ld to render a uint32_t as 32 bits. When ported using Code composer the printf with...

RE: MSP430FR59941: Boundary scan and testing
Correct: Device ID is in TLV table. In the section 6.14 of the device datasheet MSP430FR599x, MSP430FR596x Mixed-Signal Microcontrollers datasheet (Rev. C) , you can find the memory address for the device ID.

MSP430FR59941: MSP430 default GPIO state before SW is loaded
Part Number:
MSP430FR59941
Hi I would like to know the following regarding the MSP430: At power up, what is the state of the GPIO before the content of the device is active. (Before the SW on the uController starts to operate). Is there a default...

MSP430FR59941: Can not enter BSL I2C mode when Vcc is 2.2 V
Part Number:
MSP430FR59941
Hi, In the
MSP430FR59941
datasheet, it said MCU can run at 2.2V or 3.3V. But my customer set Vcc to 2.2V and it can not enter BSL mode to download program via I2C by external main chip. After testing, if VCC set to 2.9V...

RE: MSP430FR59941: MSP430 JTAG support for boundary scan
No. There is BYPASS command, but EXTEST and SAMPLE / PRELOAD is not supported. https://blog.asset-intertech.com/test_data_out/2016/09/boundary-scan-test-on-the-ti-msp430.html
